here my second request, howto give a surface a metalic effect, but not as blinking as chrome.(like the metal of a CD-Deck)

Thanx,

Daniel.

same as before. use chroming approach.

metallic appearance is primarily perceived from the shininess of a surface, in particular from the size of the specular highlights.
moreover, metallic surfaces have a highlight color depending also on the material.
dielectrics like plastic instead have the highlight color equal to that of the light shining on them.

*normally*

let's try to simulate a copper appearance.

use a diffuse texture where the average color is about (0.8,0.51,0.33)

the chrome texture has to be blended with the metallic specular color, about (1,0.7,0.6).

note that there is not a way to be sure that a particular metodology of rendering will show up a desired appearance.
in computer graphics, quantities such as colors, lighting and the like have to be tested and optimized to achieve the best result.
